Abstract (en)

[origin: US5019260A] A porous polymeric medium having a low affinity for amide group-containing and adjuvant-containing materials is provided comprising a porous polyvinylidene difuoride substrate and a surface-modifying polymeric material having a low affinity for amide group-containing materials formed in situ at and covalently bonded to the surface of the porous polyvinylidene difluoride substrate, the surface-modifying polymeric material being formed from a monofunctional monomer having at least one hydroxyl group. Another embodiment that provides a porous polymeric medium having a low affinity for amide group-containing materials employs a supplemental monomer in combination with the monofunctional monomer having at least one hydroxyl group to form the surface-modifying polymeric material. The supplmental monomer or comonomer used is one which, when formed as a homopolymer, has a high affinity for amide group-containing materials.
